White orthorhombic crystals; refractive index 2.199; density 5.85 g/cm3; melts at 501°C; vaporizes at 950°C; partially soluble in cold water (6.73 g/L at 0°C and 9.9 g/L at 20°C); KSP 1.17x10-5 at 25°C; moderately soluble in boiling water (33.4 g/L at 100°C); slightly soluble in dilute HCl and ammonia; insoluble in alcohol. | [Occurrence]
Lead dichloride occurs in nature as the mineral cotunnite. The compound is used in making many basic chlorides, such as Pattison’s lead white, Turner’s Patent Yellow, and Verona Yellow, used as pigments. Also, it is used as a flux for galvanizing steel; as a flame retardant in nylon wire coatings; as a cathode for seawater batteries; to remove H2S and ozone from effluent gases; as a sterilization indicator; as a polymerization catalyst for alphaolefins; and as a co-catalyst in manufacturing acrylonitrile. | [Definition]
ChEBI: An inorganic chloride consisting of two chlorine atoms covalently bound to a central lead atom. | [Preparation]
Lead dichloride is precipitated by adding hydrochloric acid or any chloride salt solution to a cold solution of lead nitrate or other lead(II) salt:
Pb2+ + 2Clˉ → PbCl2
Alternatively, it is prepared by treating lead monoxide or basic lead carbonate with hydrochloric acid and allowing the precipitate to settle.

Safety equipment suppliers/manufacturers can pro-vide recommendations on the most protective g love/cloth-ing material for your operation. All protective clothing(suits, gloves, footwear, headgear) should be clean, avail-able each day, and put on before work. Work clothingshould be HEPA vacuumed before removal. Contact lensesshould not be wor when working with this chemical. Weardust-proof chemical goggles and face shield unless fullface-piece respiratory protection is worn. Employees shouldwash immediately with soap when skin is wet or contami-nated. Provide emergency showers and eyewash. | [Purification Methods]
Crystallise it from distilled water at 100o (33mL/g) after filtering through sintered-glass and adding a few drops of HCl, by cooling. After three crystallisations the solid is dried under vacuum or under anhydrous HCl vapour by heating slowly to 400o. The solubility in H2O is 0.07% at ~10o, and 0.43% at ~ 100o. |
| Questions And Answer | Back Directory | [Chemical Properties]
Lead(II) chloride is a white crystals or powder. Insoluble in cold water; soluble in hot water. It is an inorganic compound with the chemical formula PbS. It is also known as galena, which is the principal ore and important compound of lead. It is one of the earliest materials to be used as a semiconductor as it tends to crystallize in sodium chloride. Lead sulfide is toxic if it is heated to decomposition, which forms lead and sulfur oxides.
Lead(II) chloride has been used in the synthesis of methyl ammonium lead iodide perovskite nanocrystals with potential application in optoelectronics due to its tuneable electronic bandgap and superior photovoltaic performance. It may be used in the preparation of mixed halide perovskite (PRV) with potential application in absorber layer of PRV solar cells. Lead chloride is used as a precursor material in the fabrication of methyl ammonium lead iodide-chloride (MAPbI3-xClx) perovskites.
| [Uses]
Lead (II) chloride is also known as lead chloride, lead dichloride, and plumbous chloride. Lead chloride is one of the most important lead-based reagents. It occurs naturally in the form of the mineral cotunnite. The solubility of lead chloride in water is low. Lead (II) chloride is the main precursor for organometallic derivatives of lead. Lead chloride has extensive applications in industries. Lead chloride is an intermediate in refining bismuth (Bi) ore. The ore containing Bi, Pb, and Zn is first treated with molten caustic soda to remove traces of acidic elements such as arsenic and tellurium. The molten lead chloride is used in the synthesis of lead titanate (PbTiO3) and barium PbTiO3. It is used in organometallic synthesis to make metallocenes, known as plumbocenes. Lead chloride is used in production of infrared transmitting glass and in production of ornamental glass called aurene glass. This stained glass has an iridescent surface formed by spraying with lead chloride and reheating under controlled conditions. Stannous chloride (SnCl2) is used for the same purpose.
| [Reactions]
Lead(II) chloride reacts with chlorine to produce Lead(IV) chloride: PbCl2+ Cl2→PbCl4.
